In a rare show of diplomacy between the two Koreas, Kim Jong Un's younger sister is traveling to South Korea on Friday for the opening ceremony of the 2018 Winter Olympics in Pyeongchang.
Her journey will be a milestone of historic significance — she'll be the first member of North Korea's ruling family to visit the south since the Korean War in the 1950s, according to The New York Times.
Like her brother, and much of the rest of their family, few details are known about Kim Yo Jong and the life she lived before reaching a prime leadership role in the North Korean government.
Here's what we know about her so far:

Like many of Kim's family members, Kim Yo Jong's exact age is difficult to pin down. But she's believed to be between 29 and 31.
She's the youngest child of former North Korean leader Kim Jong Il and his consort Ko Yong Hui, a former dancer.

She was partly educated in Switzerland, at the same school Kim Jong Un attended. But she returned to North Korea in 2000 after completing the US equivalent of the sixth grade.
